  • avfilter/vf_blackdetect : support full-range YUV

    avfilter/vf_blackdetect : support full-range YUV
    

    This filter currently makes the distinction between limited and full
    range by testing for the deprecated YUVJ pixel formats at link setup
    time. This is deprecated and should be improved to perform the detection
    based on the per-frame metadata.

    Rewrite it to calculate the black pixel threshold at the time of
    filtering a frame, when metadata about the frame's color range is known.
    Doing it this way has the small side benefit of being able to handle
    streams with variable metadata, and is not a meaningful performance
    cost.

  • Accurately calculate concatenated audio file size without actually concatenating for rss enclosure length

    19 décembre 2024, par askrill

    A little background. Im working on implementing DAI into a podcast hosting and the solution I’m working with is splitting the audio file for mid role ads and then just concatenating the files with the ad in middle. All files will be the same encoding, bitrate… what I need to figure out is what to put as the length of the encloser in the rss feed. In addition if the ad is gonna change per request then there’s no way to keep that encloser length accurate unless all the ads are the same size.

  • avformat/matroskadec : Accept more unknown-length elements

    17 mai 2019, par Andreas Rheinhardt
    avformat/matroskadec : Accept more unknown-length elements
    

    The current Matroska specifications mandate that only two elements may
    use an unknown-length length : Segments and clusters. But this was not
    always so : For the greater part of Matroska's existence, all master
    elements were allowed to make use of the unknown-length feature.

    And there were muxers creating such files : For several years
    libavformat's Matroska muxer used unknown-length for all master
    elements when the output wasn't seekable. This only stopped in March
    2010 with 2529bb30. And even afterwards it was possible (albeit
    unlikely) for libavformat to create unknown-length master elements
    that are in violation of today's specifications, namely if the master
    element was so big that the seek backwards to update the size could
    no longer be performed inside the AVIOContext's write buffer. This
    has only been fixed in October 2016 (with the patches that introduced
    support for writing CRC-32 elements).

    Libavformat's Matroska demuxer meanwhile has never really supported
    unknown-length elements besides segments and clusters. Support for the
    latter was hardcoded. This commit changes this : Now all master elements
    for which a syntax to parse them is available are supported. This
    includes the files produced by old versions of libavformat's muxer.

    More precisely, master elements that have unknown length and are about
    to be parsed (not skipped) are supported ; only a warning is emitted for
    them. For normal files, this means that level 1 elements after the
    clusters that are encountered after the clusters have been parsed (i.e.
    not because they are referenced by the seekhead at the beginning of the
    file) are still unsupported (they would be skipped at this point if
    their length were known).
